Reviews & Ratings for Bushmaster XM-15 Complete Upper w/Bolt 300 AAC Blackout Flat Top M4-Profile 16 in.Barrel w/ Rifle Length Quad Rail (7 in. Pistol Length Gas Tube) Pre-Ban — 1 review — Page 1

I searched for a Bushmaster 300 Blackout upper to go along with the complete Bushmaster ORC 5.56/.223 that I own. I bought an Anderson lower and will swap out the stock with a Magpul ACS-l stock. I loved that this 300 upper came ready installed with the quad rail which I had to buy separate and install for my Bushmaster 5.56. So it's ready for the scope, bi-pod & vertical hand grip right out of the box. Prices for this product were either a bit higher than Optics Planet, or out of stock, so I think I got a good dela.
